ROBERTS 70-115 Moisture Barricade Underlayment Film – 6 Mil, 120 Sq Ft Roll for Vinyl, Laminate, SPC, Engineered Wood

Overview

Designed for vinyl, laminate, SPC, and engineered wood flooring installations, the ROBERTS 70-115 Moisture Barricade Underlayment Film delivers a durable moisture barrier that helps create a stable, predictable base beneath your flooring. Made from polyethylene, this 6 mil thick sheet offers rugged protection while remaining flexible enough to mold to subfloor contours and room layouts. The result is a reliable, user-friendly layer that supports a clean, professional-looking floor.

With practical dimensions and features tailored to real-world jobs, this underlayment rolls out efficiently and minimizes the need for excessive seaming. The black film not only looks tidy on site but also helps conceal minor subfloor imperfections during the early stages of installation. An adhesive strip is included to seal seams, reinforcing the barrier against moisture at joints where two sheets meet.

What to expect on site

This underlayment aims to simplify moisture management during flooring installations while supporting multiple flooring systems. It is designed to pair with existing underlayment where applicable and to offer a practical, reliable barrier rather than make guarantees about performance outcomes. Consider it a protective layer that can contribute to a cleaner, more stable install when used as part of a complete flooring plan.
